IAM PRovEMENT IN CAR-BURETERS.

Specification forming part of Letters Patent No. `207,886, dated September 1:0,71878'g application iiled May 28, 1878.

To all whom it may concern:

Be it known that I, THEonoRE MINER, of

Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Garbureters, of which the following is a specification:

Figure lis a vertical section of my improved carbureter, taken through the line a' w, Fig. 2.

Fig. 2 is a horizontal section of the same, taken.

through the line ,y y, Fig. 1. Fig. 3 is a detail sectional view of Aone of the distributers. Fig. 4 is a detail sectional view of the'feed-valve.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved carbureter which shall jbe so con-` structed as to feed the naphtha automatically to the carbureting-chambers as it may be required, which will introduce the gas into the warmer part of the carbureting-chambers and will withdraw it -from the colder part, and

which at the same time shall be simple in construction and reliable in operation, not being liable to become choked or clogged.

The invention consists in the oat-sleeve provided with cup at the top and( combined with the feed-pipe; and in the drum provided with a discharge-pipe extending between chamber and reservoir, as hereinafter described. g

A represents the case of the carbureter, in theV upper part of vwhich is secured a tank or reservoir, B, to receive the naphtha, which is introduced through a pipe, C. The pipe G eX- tends nearly tothebottom of the reservoir B, and its upper end passes up through the top of the said reservoir and the top of the case A.

D is a short pipe passing through the top of the reservoir B and the top of the case A, to allow air to escape from the reservoir as the naphtha is poured in.

rlhe upper ends of the pipes C D project above the top of the case A, and are surrounded by a cup, E. The upper ends of the pipes C D are covered with caps F, the sides of which project nearly to the bottom of the cup E, so as to be'beneath the surface of the water placed in the said cup, to form a waterseal and prevent the escape of vapor or the entrance of air through the said pipes. The

`cup E is provided with a cover,vGr, toy'p'revent the water withinitgfrom' evaporatipg.

From the reservoir B,the naphtha..passes out through the pipe ,Hjinto the .feed-well I, and in` the center of the said j feed-well' it is bent `downward at right angles, and extends nearly t0 the bottone.o'f-` the Sandwell.; .The upper part of the pipe H- is provided with a stop-cock, J, to enable the escape of jnaphtha to be stopped when jdesired, the coverof well I being removable, ,.-A y Y From thewellrl a pipe. K, passes .into the reservoir B, and extends up nearly "to,Y itstop, for the lpassage of air orvapor from ene to the other ofthe saidvessels' to equalize the pressure.

The lower part of the pipe H passes down through a pipe, L, which is made so much larger than the said pipe H that the naphtha may lflow out ofthe lower end of the pipe H and rise through the space between it and the pipe L.

To the upper end of the pipeL is attached a cup, M, into which the naphtha rises, and from which it flows through a small-spout into a cup, N, attached to the end of a pipe,-O,leading into the carburetingchambenj l 1 Upon the lower part 'of the pipe L is formed a screw-thread to receive a screw-thread formed upon the sleeve or h ub of theiloat P.j

With thisA construction, whenthe naphtha rises in the well I above the .fixed limit, the float P rises and brings a packing placed in the lower end of the pipe L against the open lower end ofthe pipe H, and stops theouttlow of the naphtha. l

When the naphtha risesv in the carburetingchamber tol the4 desired` heightitoverliows the cup N and falls into the lower part of the well I. When more than one carburetingchamber is used the lower chamber or cham` bers are provided withV feed-pipes O opening into the lower partof the well I, so that the naphtha in the lower part of the said well mayr flow through it into the said chamber.

Q represents the carbureting-chambers, one

secured in the lower part of the case A, below the reservoir B. The carbureting-chambers Q are made ring-shaped, and are divided into or more of which may be used, and which are two concentric rings, which rings are divided by partial partitions into circles of zigzag compartments, as shown in Fig. 2, so that the gas may pass all around through the said compartments.

In each of the compartments of the carbureting-chambers Q is placed a distributing device, R, consisting of a number of wicks extending from the upper part of said chambers, or from a plate in said upper parts, nearly to their bottoms, a space being left below the lower ends of the said wicks to prevent the heavy oil in the bottom of said chambers from coming in contact with the said wicks and impedin g their operation.

To the lower part of the sides of the earburetingchambers Q are secured ring-pipes S, into which the naphtha from the feed-pipes O passes, and from which it escapes into the carbureting-chambers through numerous small holes formed in the inner side of the said pipes and leading into the said chambers, as shown in Fig. 2. By this arrangement the naphtha is introduced into the warmest part of the earbureting-chamber, so that it will not be chilled at its iirst introduction and thus ren dered less easily vaporized.

Inthe center of the carbureting chamber or chambers Q is formed a cylindrical drum, T, the lower end of which does not extend quite to the bottom of the carbureting-chamber Q, or has openings in its lower part, so that the heavy oil from the said chamber may iow into the lower part of the said drum,'pass into the chamber U, and low through the inclined pipe V into the lower part of the well I, whence it may be removed as desired.

The lower edge of the drum T should extend below the surface of the naphtha in the lower carbureting-chamber, so that the gas cannot pass around the said lower edge.

The gas is introduced into the carbureter through a pipe, W, leading into the first compartment of the carbureting-chamber, or the first compartment of the outer ring ofthe carbureting-chamber, or of the lower carburetingchamber when more than one is used, whence it passes through all the compartments of the outer ring, then into the iirst compartment of the inner ring, through all the compartments of the said inner ring, and into the upper carbureting chamber when more than one is used, through a pipe, X, being introduced into the first compartment of the outer ring of the said upper chamber. The gas passes through the upper chamber, Q, in the manner hereinbefore described, and escapes from the last compartment of the inner ring through an opening in the upper particil the drum T.

From the drum T the enriched gas passes out through the pipe Y to the burners. The pipeY leads out of the top of the drum T, and passes out through the space between the bottom ofthe reservoir B and the top of the carbureting-chamber Q.

By this construction the gas is introduced into the warmer part of each carbureting-chamber, passes thence to the colder part of said chamber, and escapes into the drum T, which is the coldest part of the apparatus, and passes thence through the pipe Y to the burners.

By this construction the gas will not be chilled upon its first introduction into the carbureter, and be thus prevented from becoming properly enriched. At the same time the gas escapes from the coldest part of the apparatus without contact with any of the walls or partitions of the carbureting-ehambers, so that all condensable vapor is removed from it before it passes into the pipes, so that the snpply-pipes will not be liable to become filled or choked with naphtha from condensation.

The pipe Y is so arranged that the combined gas and vapors, after being carried to the center or coldest portion of the machine, may be passed out without coming in contact with any portion of the machine by which its temperature can be a'ected.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Iatent l. The float-sleeve L, provided with cup M at the top, and combined with the feed-pipe H, as and for the purpose described.

2. The drum T, provided with a dischargepipe, Y, extending between the chamber Q and reservoir B, as and for the purpose speci-l fied.

3. The combination of the ring-pipe S, provided with discharge-holes in its inner side, with the feed-pipe O and the outer circle ot' compartments of the carbureting chamber or chambers Q, substantially as herein shown an d described. i
